This is just a heads up to let you know that in the next couple of days
I'll be committing a fairly large, but simple, diff which rearranges the
scheduler a little.
Here's the scoop:
- Global scheduler state has had meaningful prefixes
put on the names: sched_whichqs, sched_qs, sched_slpque.
This is to help identify them as global scheduler state.
The declarations have also been centralized in kern_synch.c
- Per-cpu scheduler state moved into struct schedstate_percpu:
runtime, curpriority, and what was p_schedflags.
- cpu_info structure and the curcpu() macro are now mandatory,
and I have added one to all ports. The definition of cpu_info
has also been simplified a little.
- All references to per-cpu scheduler state are now made through
This is just a first sweep -- there's a bunch of general scheduler
cleanup to do before we can actually schedule processes on different
If you have any objections, then you'd better speak up now -- I'm only
going to sit in this for a couple days before it goes in.
